This clear oil is thicker and more syrupy than others, and it smells faintly like flowers.

WHY WE LIKE IT:

Though kind of globby out of the dropper, this oil is almost unnoticeable in medium to thick hair. (We don't recommend it for fine hair; it made one tester's hair flat.) You feel none of the telltale slickness or sleekness of traditional oils. Instead, it made our hair shiny, incredibly soft, and bouncy (just don't get it near your scalp; it's still oil.) Now, as tempting as it may be to apply this stuff every day, don't—the editors who did ended up with a dull residue by day four. Stick to three times a week, max. Also, you don't need much: a dime-size amount in thick, shoulder-length or longer hair; a pea for everyone else. If you do happen to OD (on this or any other oil), massage a clarifying shampoo into dry hair before stepping into the shower, so the cleansing agents can get to work before being diluted by water, advises New York City hairstylist Nunzio Saviano. It's a trick that's saved our testers time and time again. (This formula is free of parabens, sulfates, phthalates, and synthetic color.)
